Tanning is more of a leisure activity than anything else is. People actually just care about the result, not really the means of getting it. You can say that for only a very few things in this world. For those who can afford to waste hours and days to get a tan, all very well, but what about those people who do not even have enough time to watch a movie. They can get their tanning done at home with the help of a self-tanning cosmetic. It takes surprisingly little time to apply and then only a few hours to develop. All you have to do is to apply it in the night and leave it on before you sleep. In the morning you will get that gorgeous tan. If you choose a good product, there will be absolutely no question of smudging or spreading.
When it comes to the modes of application of these self-tanning products, you will find a few different ways. Either you can buy a normal lotion that you will normally apply on your skin or you can choose a roll-on or a spray mist kind of application. In the spray, you can keep on getting refills for the sprayer; this gives you by far the most even application of tan. Then there is also the aerosol can, which is simply a quick fix or an urgent repair job mode of tanning.
These tanning cosmetics give a very long-lasting tan and will last a decent amount of time before you need to apply them again. They last for a week comfortably; and do not worry; they do not wash away while having a bath or if they get wet.
It is advisable that you take proper advice from your dermatologist about applying these cosmetics if you are prone to any skin allergies or have any skin disease.
